Powershell variables

[benmyers]

Hi, I am parsing invoices and would like to print the pdf.

I am using the powershell command below but keep receiving this error.

Invoke Power Shell: Cannot validate argument on parameter 'FilePath'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

"Start-Process -FilePath $fname -Verb Print"

I have powershell variable setup and an assign before it

strfullpath = strDocPath +"\" + FileName

fname - in - string - strfullpath

Any help would be appreciated.
